Grep test 15 / 17
How does purgeCSS work? It simply checks for a predefined regex and compares it with Tailwind's classes.
For correct purging avoid dynamically computing class names like 'rounded-' + (this.lg ? 'lg' : 'sm').
Instead properly type out each class: this.lg ? 'rounded-lg' : 'rounded-sm'.
Note: This will also help you find code easily. It's always a good idea to make your code pass the so called "grep test".
Try fixing the issue by properly writing out both class names.
